JE Pistons are a popular aftermarket upgrade for the S65 engine. JE Pistons specialize in high-performance forged pistons designed to withstand the extreme demands of motorsport and performance builds. When used in the S65, they offer the following benefits: Increased Strength: Forged from aerospace-grade aluminum alloys, JE pistons are much stronger than cast pistons, capable of handling higher compression and power levels. Lightweight Design: They reduce reciprocating mass, improving throttle response and engine revving characteristics. Customizable Compression Ratios: JE Pistons can be tailored to specific performance goals, such as higher compression for naturally aspirated builds or lower compression for turbo or supercharged applications. Improved Durability: JE's pistons are designed to handle high heat and stress, making them ideal for high-revving engines like the S65.
